FLIGHT CONTROL EQUIPMENT

CROUZET provides electromechanical actuators for aerospace utility control applications, such as entry door actuators, oil cooler air trap actuators, engine and APU disconnect actuators, APU inlet door actuators, and a host of other aircraft utility applications. CROUZET engineers work with customers for requirements validation for each application. Our utility actuators use RVDTs, potentiometers, and resolvers to capture motion information and interface with the flight control computer.

With more than 14,000 actuators flying, each with a proven MTBF greater than 15,000 FH, CROUZET has the technology, experience and capability to provide a more optimized unit in terms of system weight, cost, aircraft integration, reliability and maintainability. 

CROUZET actuators are designed for safety with the inclusion of over torque limitation, dual load paths and redundant sensors – all according to application requirements. Further, all electrical components used are mature components – logging flying hours for more than 20 years.

We are accustomed to working with both aircraft and system manufacturers in a collaborative environment. When coupled with our extensive and capable on-site test facility, CROUZET is able to support all systems requirements, from development to certification, within the program schedule.

CROUZET is both an OEM and MRO solution provider.

Our spoiler electromechanical actuator (EMA) is powered by an electrical network. One or two electric motors drive a linear screw that is capable of moving the spoiler surface and holding the required position. Several concepts have been evaluated to meet various aircraft applications, architectures and certification requirements.

Our EMA solutions offer an alternative to what is commonly used in existing aircraft – hydraulic actuators that move various surfaces, such as spoilers. While hydraulic technology is mature, it requires multiple hydraulic pumps and a network of hydraulic pipes and valves – all with high weight and maintenance cost implications.

Further, fluid contamination can lead to common failure modes at the aircraft level and oil leakage above a hot brake could possibly even create fire. The good news is that the current aerospace industry trend is toward more electrical systems on aircraft. New power sources now allow more aircraft surfaces to be driven by electro-mechanical actuators (EMA). Our actuators can be deployed in either fly-by-wire or conventional flight control systems.
